 We have a policy of not buying new where we can avoid it and with the office furniture for example what we have discovered is that you can get very high quality office furniture for a fraction of the new cost and ultimately we found that what we would have spent on new we can actually get something much higher quality for the same price so I'm sitting on a 700 pound office chair that cost me 150 pounds and I'm very happy about that. Perhaps in your business you could look at the capital items that you are spending a large amount of money on and look at whether you actually need to buy new or whether there's an alternative that's used and actually can give you a business benefit as well as reduced emissions.
